The present invention relates to improvements in sewer construction-and constitutes a division of my similarly-entitled,co-pending application,-Serial No.Y 47,281, filed July 3l,

An object of the invention is to provide a sewer construction having a guard therein for arresting bodies, and in providing, in conjunction with the guard, a man-hole giving ,10 access to the guard and whereby bodies arrested by thev guard may be withdrawn from the sewer.

Another object of the invention lies in providingguard means for trappingbodies to indicate where such bodies have been thrown intothe sewer. s

. The invention furtheraims tok provldeV a guard which admits of ready opening and closing and which may be left in the perma- 2o nentlyy open position if desired.

Y With! the foregoing and other objectsj in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto. Y

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure l is a vertical sectional view taken 3o through a catchbasin, sewer system and a guard arrangement constructed in accordance with the invention described and claimed herein;

Figure 2 is a cross sectional view taken :i5 through the sewer adjoining a guard;

Figure 3 is a vertical section taken on the line 3-3 in Figure 2;

Figure 4 is a view similar to Figure 2, showing another form of guard; and

Figure 5 is a vertical section taken on the line 5-5 in Figure 4.

Referringmore particularly to Figure 1 of the drawings, 48, 48a designates a perforated cover the horizontal part of which is shown as seated upon a shoulder 49 ofthe horizontal part of a fra-me 50. The frame is shown as fitted upon the upper end of the wall 5l of a basin 52. The vertical part v481i of the cover will extend up within an opening Y 5o in the curb. The horizontal part 48 of lthe cover is shown as provided with trunnions adapted to enter suitable slotsV in the horizontal part of the frame 50. The curb is shown as provided with a `cutout portion 54.

By raising the horizontal part 48 of the cover the cover as a wholeV may bel rocked on the trunnions and the opening intothe receiving basin may be uncovered. "Nhen the horizontal part of the cover has been rocked suliicient-ly far it will rest against the curb.` The raising upof the horizontal part 48 will cause the vertical part 48a to move in the cutout portion 54 and this cut out portion 54 will be so shaped as not to interfere withthe .move-y ment of the vertical part 48a therein. While the cover 48, 48a. is shown as circular in shape it will, of course, be understood that the cover `may be of anydesired shape and that the frame 50` may be `made to conform to the shape of thecover.

As much of the basin as may be desired may be built under the sidewalk leaving only, if

desired, an opening in the street sufficiently large to permit an operator to enter the basin,

and, if desired, instead of a perforated cover of the type shown inthe drawings any suitable-opening and cover to the basin may be provided. 'I

Within the basin'52 there is shown a ladder V5,5 appropriately supported to enable opera-tors to descend into the basin when the cover of the basin is lifted. Pipes 59, 60 and 6l are shown as leading downwardly and lout of the basin 52 at variouselevations.

Y downwardly and into the basin 52 and may carry fluid from another ,basin or any higher level. The pipes 60 and 61 may be made in one pieceif desired. v

Thesewer 62 is shown as provided with a guard 64, this guard being shown as in the shape of a perforated door hinged4 at its upper end as indicated at 65. While l have shown the guard 64 as hinged at 65 the guard 64 may be hinged at any desired point in the upper part of the sewer. ,The guard 64 may abut. at its lower en d againsta step which mounted at any appropriate point in the..

sewer. rIlhe sewer is accessible through a man hole 68 at Vthe surface by a cover 7 0. An extension ladder 7lv may be provided to let downinto the sewer from the man hole. p a

The guard 64 is desirable for discovering bodies that may have been thrown into a sewer and` for locating the points at or about which these bodies were deposited. The pipes 59, GO and 61 leading away from the basin 52 may be provided with traps consisting of perfo-rated plates S-larranged over the mouths of the pipesv and doors 86 perforated at their lower portions as indicated at 90. These traps form the subject matter of a separate application.

In Figures 2 and 3 a slightly different form of guard is shown. In these figures 7 3 designates a ring, shown as having openings therein and as having a cent-ral orilice normally closed by a pair of doors 74 and 75, the doors being shown as of an open work construction, and as being hinged, as indicated at 76 and 77, to opposite portions of the ring 7 3. A latch 78 is shown as provided for holding the doors in a closed position. The doors may be opened whenever necessary or desirable. As shown in Figure' 2, the latch78 may be pivoted at one end and swung upwardly to engage over depending'alined projections carried by the doors 74 and 75, although any other desired. fastening means may be used in the combination for securing the doors in closed position if desired.

IVhile the doors are shown as rounded, the ring 73 may be so shaped thatthe door intended to fit in the ring may be made rectangular or in one piece, and the door maybe hinged to a side or upper part of the ring.

In Figures 4 and 5 a further form of door is shown. In these figures 79 indicates a sewer shown as rectangular in cross section and as havinga rectangular door 80 mounted therein and hung from a pintle Sla-beve. In this case there is shown` astop 82= against which the lower free end ofthe rectangular door may abut. The 'door' is shown asl provided with numerous slots therein forjtl'ie passage of Huid. Instead of hanging the door from the pintle 81 the door' maybe hinged to one side ofthe-sewer'. p

It will, ofcurse, be understecdtliat instead of. using stops as'f or 82 at the: bjottonr cfa sewer, stopslmi'ght be provided at the sidesor' any other' suitable pointsinthesewer, orithe sewer might be providedfwitfr a shoulder in which is shown as placed ladder 69, the man hole being shown as closed against which the guard might abut, and, instead of a latch, as 78, the ring 73 might have a shoulder formed thereon against which the guard may abut.

It will, of course, be understood that sewers are ordinarily constructed with' an incline towards the poi-nt of discharge and this inclination of the sewer will tend to hold the guards vclosed. When guards are used in sewers' so constructed no means need be provided for holding the guards in closed position, but, if desired, any suitable means might be provided to aid in holding the guards closed. I

It is obvious that various changes and modications may bevmade' in the details of Vconstruction and design ofthe above speciali'- cally described? embodiment of this invention without departing from' the spiritthereof'.

IV hat is claimed is :--Y

l. In a subterranean sewer, a sewer pipe, a manhole leading from the surface down tothe sewer pipe, aforamiirous guard located in the sewer pipe at the remote side of the manhole with reference to the direction of ow'of the Water, means whereby-saidguard is'pivotally supported for opening movement against the current of water, and means for holding the guard secureld'in the'v closed position. f 7

2,. In a subterranean sewer, asewer pipe, a manhole leading to tliepipe', 'a' perforated guard secured in the pipe adjacent the man'- hole, a pair' of pivot'edd'oors mounted? said guardand adapted to abut against the parts of the guard", andmeans engaging alined p0rtion'slof the closed doors for securing sa-me in closed position.
